【 摘 要 】

A tetrameric inhibitor that is active against α-amylase from the larvae of the insect Tenebrio molitor, but inactive against the enzyme from human saliva and against the endogenous one, has been described in barley endosperm. The subunits of the inhibitor have been identified as the previously characterized proteins CMa, CMb and CMd, of which only CMa was inhibitory by itself.
